QlgStatvfs64()--Get File System Information (64-Bit enabled and using NLS-enabled path name)

  #include <sys/statvfs.h>

  int QlgStatvfs64(Qlg_Path_Name_T *path,  
                 struct statvfs64 *buf

The QlgStatvfs64() function, like the statvfs64() function, gets status information about the file system that contains the file named by the path argument. The difference is that the QlgStatvfs64() function takes a pointer to a Qlg_Path_Name_T structure, while statvfs64() takes a pointer to a character string.

Limited information on the path parameter is provided here. For more information on the path parameter and for a discussion of other parameters, authorities required, return values, and related information, see statvfs()--Get File System Information.

Parameters

path

(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name or a pointer to a path name of the file from which file system information is required. For more information on the Qlg_Path_Name_T structure, see Path name format.
